3 Claims.

My invention relates to a hot and cold water mixing attachment, and hasfor its purpose to provide a device that can be quickly positioned inoperative relation to a pair of separate hot and cold water faucets soas to enable drawing a mixed supply of water from one outlet and therebyattaining any desired temperature.

A further object of the invention is to provide a practical structurethat is economical to produce and can be applied to the hot and coldwater faucets of conventional basins without the need of special toolsor equipment.

Another purpose of the improvement is to provide an attachment that canbe temporarily secured and quickly removed when desired, also one whichis applicable to differenttypes of faucets and adjustable to accommodatevarying conditions, as where faucets are arranged at varying distancesfrom each other.

To these and other ends, the invention comprises the construction andarrangement of parts that will appear clearly from the followingdescription when read in conjunction with the accompanying drawing, thenovel features being pointed out in the claims following thespecification.

In the drawing:

Fig. 1 is a perspective view illustrative of a preferred embodiment ofthe invention and showing it in operative position;

Fig. 2 is a front elevation of the attachment removed from the basinfaucets.

Fig. 3 is an enlarged side elevation, partially in section, showing themeans by which each elbow is held in operative relation to its faucet;

Fig. 4 is a side elevation of one of the elbows and its connection tothe union, and

Fig. 5 is a detail sectional view on line 5-5 of Fig. 2.

Referring more particularly to the drawing in which like referencecharacters refer to the same parts throughout the several views, 1designates a conventional basin and'2 are the hot and cold water faucetshaving spouts 3 to which the attachment is secured.

The invention, may be practically applied in a variety of ways, and inone preferred embodiment, as herein disclosed, includes a hollow union4' having an outlet spout 5 that may be threaded on the upper end of theunion 4, while 6 designates inlet branches or pipes preferably formedintegral with the hollow coupling 4 and extending downwardly andforwardly at an angle to each other as shown.

Each of the hollow pipes 6 is adapted to receive a conductor or pipe '7which has secured to its outer-end an elbow 8 preferably threadedthereon, the latter terminating in an enlarged coupling 9 adapted tosurround the outer end of the spout 3, as shown in-Fig. 3. 10 designatesa washer seated in the coupling 9 and engaging the outer endof the spout3.

The elbow 8 and coupling 9 are held removably in operative engagementwith the spout 3 by any suitable device such for instance as thebifurcated clamp 11, the arms of which engage around the elbow 8 onopposite sides thereof'and under the shoulder formed by coupling 9, asshown in Fig. 3. The clamping member 11 is pivoted in one of theopenings 12 to a strap 13 that surrounds the horizontal portion of thespout. 15 designates a'tightening screw threaded in the arm 16 at therear end of the clamping member 11 and adapted when turned to engage thelower side of the spout 3 and to force the arm 16 downwardly while atthe same time projectin the bifurcated clamping member 11 upwardly andholding the coupling in tight engagement with the spout 3. 17 designatesa knurled disk secured permanently to screw 15 for permitting readyadjustment of the latter.

Each pipe or conductor 7 leading from the elbow 8 is slidably ortelescopically engaged in the branch or pipe 6 and held in adjustedposition by means of a nut 21, see Fig. 5, having a knurled operatingportion 22. The inner end of the nut 22 engages a metal washer 23 whichin turn engages a rubber or fiber washer 24, compressing the latter whenthe nut is turned inwardly and thereby effecting a tight joint aroundthe pipe 7.

By having the pipe '7 slidably adjustable in the branch 6, the devicecan be applied to any of the different conventional types of basinsirrespective of the distance or angular relation between the twofaucets. Where the latter are farther apart, the pipes '7 are not movedquite so far into the branches 6 of the union, and where the faucets arecloser together, the pipes are telescoped farther into the branches 6.Then by tightening the nuts 21 and the clamping members 11, the deviceis held in operative relation and will continue to function as long asrequired. To remove the attachment, it is only necessary to release theclamping members 11, and the device can then be dropped downwardly awayfrom the spouts 3. The entire structure an be quickly assembled inoperative relation, nd affords a practical and efllcient device thatequately takes the place of any combination faucet, at a minimum expenseboth of manufacture and assembly.

While the structure has been described with reference to a particularembodiment, it is not confined to the details t forth herein, and thisapplication is intended cover any modifications or departures comingwithin the purposes of the improvement or the scope of the following Iclaim:

1. A universal hot and cold water mixing attachment, comprising a hollowunion having an outlet connection, inlet branches integral with saidunion and inclining downwardly, forwardly and laterally therefrom, saidinlet branches forming an obtuse angle with each other, conductorstelescopically arranged in said inletbranches and adjustable endwise androtatiyely therein, elbows fixed at the ends of said conductors havingupwardly extending portions terminating in couplings, and means forsecuring said couplings to a pair of faucets.

2. A universal hot and cold water mixing attachment, comprising a hollowunion having an upwardly and forwardly extending outlet, inlet branchesintegral with said union and inclining 1,osc,ass

downwardly, forwardly and laterally therefrom, said inlet branchesforming an obtuse angle with each other, conductors adjustable endwiseand rotatively in said inlet branches and extending downwardly in thesame direction, elbows fixed at the ends of said conductors havingupwardly extending portions terminating in couplings, and means forsecuring said couplings to a pair of faucets.

3. A universal hot and cold water mixing attachment, comprising a hollowunion having an outlet connection, inlet branches inclining downwardly,forwardly and laterally from said union and formed integral therewith,said inlet branches forming an obtuse angle with each other, conductorstelescopically arranged in said inlet branches and adJustable endwiseand rotatively therein, elbows fixed at the ends of 'said conductorshaving upwardly extending portions terminating in couplings, eachcoupling including a shoulder, and clamping members removablypositionable on a pair of faucets and engageable with said shoulders tohold the couplings thereon.
